ELECTRICAL APPLIANCE FOR PANEL-BOARDS.

I Specification of Letters Patent.

Patented Mar. 6, 1917.

Application filed July 2, 1912, Serial No. 707,147. Renewed June 23, 1914. Serial No. 846,877.

To all whom it may concern: l

' Be it known that I, RALPH E. JONES-,"Of Syracuse, in the county of Onondaga and State of New York, have invented a new and useful Electrical Appliance for Panel- Boards, of which the following is a specification.

This invention has for its object the production of an electrical appliance as a push button switch particularly applicable for use inconnection with panel boards, and it said terminal, the portion 9 extending latthe other portion of said terminal and carconsists'in the. combinations and constructions hereinafter set forthand claimed.

In describing this invention reference is bad to the accompanying drawing'in which like characters designate corresponding .parts in all the views.

Figure 1 is a plan view of the base of this electrical appliance, and parts carried thereby, the same being shown as mounted upon a panel board. J

Fig. 2 is a transverse sectional view of this electrical appliance and contiguous parts of the panel board.

Fig. 3 is a plan view of the base, the

switch being removed.

Fig. el is a perspective, view of one of the contact terminals.

' 1 is the base, which is here shown as rectangular and in the form of a box having its bottom adapted to be mounted on the I panel board, the box being open at its top.

2 is the cap or cover for the box, the cap entirely inclosiug the tpp and upright sides of the box and having its sides skirting the side faces of the box and adapted to rest upon the panel board, the cap and base having interlocking means for resisting removal of the cap and holding the cap with its lower edges engaged with the base of the panel board.

I the box 1.

3 and 4 are pairs of terminals located in 5'and 6 are swltch arms for corying spring. arms or switch contacts 11 which extend downwardly to the bottom of the box at a point spaced apart from said inner edges, and substantially midway between said edges and the opposing surfaces of ribs 14 and 15 hereinafter described. The portions 9 of the terminals of each pair are located on opposing side walls of the box .2.

As here shown the bottom ofthe box 1 includes raised ledges 12 on other opposite sides thereof on which the terminals 3, 4 are mounted and. through which the screws extend, opposing ends of each pair of terminals 3, '4 being separated by barriers 13 on said ledges 12.

The box is also formed with vertically extending ribs 1-1 projecting into theinterior thereof from the sides on which the portions 9 of the terminals are mounted, and with a rib connecting the lower ends of the ribs 1 1, the ribs 14:, 15 being located midway between the ledges 12 and serving as barriers between the terminals 3 and the terminals 4. 16 is a bridge or support forming part of the switch, the bridge extending across the upper end of the box 1 and resting at its outer ends on the upper ends of the ribs 14,

and being held in position by screws 17 .ex-

acting with the pairs of terminals 3, 4; and

' 7 and 8 are push buttons for operating the gular in form and has one portion 9 thereof engaging the inner face of one of the side walls of the box 1 and another portion lying on the bottom of the box 1 and held in position by a screw 10 extending through the bottom from the rear side thereof and into tending vertically into said ribs 1 1.

The bridge 16 supports the switch mechanism including the knife arms 5 and 6, push buttons 7- and 8 and the interposed-mechanism between the push buttons and the arms. The push buttons extend upwardly through holespin said bridge.

The base is held in position on'the panel board by fastening members, as screws 18, extending through the terminals 3, 4 and ledges 12, and threading into the offset ends 19 of bus bars 20, 21 of the-panel board,

the screws 18 serving to electrically connect. the terminals to the bus bars 20, 21 and 1nechanically connect the electrical appliance to the panel board. The heads of said screws are located within the box so that they are accessible from the front side or open top thereof. Thus the electrical appliance can be readily attached to the; panel board from the front side thereof.

The cap 2 preferably held in position screws threading into nuts 26 located in said recesses below the lugs 24.
